Trainee Glaucoma Surgery: Experience with Trabeculectomy and Glaucoma Drainage Devices

This is the authors' abstract. We don't add key points for this paper.

Background and Objective: To examine outcomes of trabeculectomy with mitomycin C and glaucoma drainage device placement for uncontrolled glaucoma when performed by resident surgeons. Patients and Methods: This study included any patient who underwent a trabeculectomy with mitomycin C (n = 93) or a glaucoma drainage device (n = 60) by a resident surgeon between 2001 and 2006. Outcome measures at 3, 6, and 12 months included failure of treatment, number of follow-up appointments, complications, number of medications, and need for further surgery. Results: One year postoperatively, intraocular pressure averaged 12.1 ± 5.1 mm Hg in the trabeculectomy group and 13.0 ± 5.1 mm Hg in the glaucoma drainage device group ( P = .31). Complications occurred in 30% of eyes with trabeculectomy and 10% of eyes with a glaucoma drainage device. Conclusion: During the first postoperative year, glaucoma drainage device surgery may have fewer complications and less morbidity than a trabeculectomy with mitomycin C when these surgeries are performed by resident surgeons. Final intraocular pressures were similar between the two groups.
